Family Planning

A six-year-old boy told his father he wanted to marry the little girl across the street. The father being modern and well-schooled in handling children, hid his smile behind his hand.
“That’s a serious step,” he said, “Have you thought it out completely?”
“Sure,” his young son answered. “We can spend one week in my room and the next in hers. It’s right across the street, so I can run home if I get lonely in the night.”
“How about transportation?” the father asked.
“I have my wagon and we both have our tricycles,” the little boy answered.
The boy had answer to every question the father raise.
Finally, in exasperation, the father asked, “What about babies? When you’re married, you’re liable to have babies, you know.”
“We’ve thought about that too”, the little boy replied. “We’re not going to have any babies. Every time she lays an egg, I’m going to step on it.”
